Turning now tothe drawings, a known tea bag packaging system 10 is shown in FIGS.1A-1C. Tea bag packaging system 10 includes an unfolded packet 20 thatcan be folded along a fold line 22 and heat-sealed to contain a tea bag30. Typically, tea bag 30 is coupled with a tag 50 via an attachmentmember 40. When a user wishes to remove bag 30 for brewing, he tearspacket 20 along a tear line 24 and removes tea bag 30, attachment member40, and tag 50. Often, tag 50 is folded over the top of tea bag 30, andcan be separated by pulling lightly on tag 50. The user can then grasptag 50 and dip tea bag 30 into a cup of hot water 60. However, uponremoving tea bag 30 from the cup, the user is presented with aninconvenient used tea bag 30.

FIGS. 2A-2C illustrates an infusion system 100 according to oneembodiment of the present invention. Infusion system 100 includes apouch 130 for holding a brewing material 132, a sealable packet 120 thathouses pouch 130, and an attachment member 140. A first section 142 ofattachment member 140 can be coupled with pouch 130, often via a pouchstaple 131, and a second section 144 of attachment member 140 can becoupled with an interior portion 121 of packet 120. Attachment member140 may be of any length, and in many cases will be long enough suchthat pouch 130 can be completely removed from packet 120 while stillbeing attached with interior portion 121 via attachment member 140. Itis appreciated that although this figure describes attachment tointerior portion 121 of packet, second section 144 can alternatively beattached with any portion of packet 120. In some cases, the portion ofpacket 120 to which second section 144 is attached is detachable fromthe remainder of the packet 120.

In use, when a tea drinker wishes to remove pouch 130 from packet 120,she can tear packet 120 along a first tear line 126, and pull pouch 130out of packet 120 or otherwise allow pouch 130 to fall out of packet 120through first tear opening 128. The tea drinker can then grasp packet120, and dangle pouch 130 into a cup of hot water 160. The tea can bebrewed while attachment member 140 is still coupled with interiorportion 121 of packet 120. When the tea is brewed the tea drinker cantear away a tab 122 of packet 120 that includes interior portion 121,typically by tearing along a second tear line 124. By holding tab 122,or by holding second section 144 of attachment member 140, the drinkercan then draw attachment member 140 through the resulting second tearopening 129 in packet 120. This action pulls pouch 130 out of cup 160and back inside of packet 120 through opening 128. As a result, usedpouch 130 is conveniently stored, and the drinker is not distracted witha messy and unsightly used pouch 130. The drinker can even use packet120 to squeeze used pouch 130 to extract the last few drops of elixirfrom pouch 130.

In some cases, infusion system 10 can be prepared with second section144 disposed externally to packet 120. Thus, after the brewing step, theuser can grasp second section 144 and pull used pouch 130 into packet120.
